Abstract (en)
[origin: EP3277045A1] Disclosed are a method and device for preempting transmission resources on unlicensed carriers, so as to implement an improved technical scheme for preempting channel resources on the unlicensed carriers, and thereby achieving a higher spectrum utilization rate. The method for preempting transmission resources on unlicensed carriers provided in the present application comprises: a device determines whether a preset clear channel assessment (CCA) detection time point is reached, said CCA detection time point being reached cyclically, said cycle being shorter than a preset allowed maximum duration of occupation for each signal transmission after the device preempts a channel; the device performs CCA detection when the CCA detection time point is reached.
